Gamblers should not focus on how many loss you can get in a row, because if you are wagering on a situation where it all depends on how many losses should be calculated and you will win accordingly, you will end up with losing that many times in a row eventually.

I have gambled for years and know enough to say that 10+ losses in a row happens all the time, it is more frequent than you could ever imagine, and the difference is, when you gamble in a method that doesn't rely on luck but simply just mathematics, you could make a bit more profit than you normally would just hoping and wishing not to lose many times in a row. Do not leave all your bankroll to luck, that will not end up with a good result and you could end up losing it all very quickly with one bad streak.
